Evalution Of A 4.5-kW D-100 Thruster With Anode Layer

Design characteristics and performance data of a 4.5-kW, thruster with anode layer (TAL) developed at the Central Research Institue for Machine Building (TsNIIMASH) are presented. The TAL is designated the D-100 with a discharge chamber of outer diameter approximately 100mm. Performance characteristics demonstrated by the D-100 and life estimates by TsNIIMASH make this thruster an excellent candidate for a wide range of station keeping, orbit raising, orbit maneuvering and JPL planetary missions.

Characterization of Kova-Pyrex Anodically Bonded Samples: A New Packaging Approach for MEMS Devices

The ability to anodically bond Kovar to Pyrex 7740 significantly expands the packaging approaches available for MEMS devices. This technique greatly simplifies and reliably interconnects micropropulsion MEMS components (thrusters, valves) with the attached propellant system.
